ICON{"name" alt="" default="name"} -- small documentation graphic or icon of common attachment types

Generates a small graphic image from the set attached to DocumentGraphics. Images typically have a 16x16 pixel size. You can select a specific image by name, or you can give a full filename, in which case the type of the file will be used to select one of a collection of common file type icons.

if you specify an icon which cannot be found, the one specified in the default parameter will be used (and if that fails, the 'else' icon will be used)
